I've recently bought a secondhand boat that is fitted with a Navman 5100 Chartplotter but it's not working. The unit will switch on occasionally and work fine but switch it off and leave it awhile and it won't switch back on. Voltage, wiring and connections seem to be fine. Power is from two 12v 70ah batteries in parallel, they're fairly old but there's plenty of power for the radio and FF.

Any GPS Gurus out there?
